[PYTHON(DJANGO), JS] Implementing a loading bar w/ large file size uploading abilities, a video bar with a buffer, quality changing, and gathering the info of a picture from the server

I'm developing a video site, I've built a basic layout of how the video bar would look like and I created basic functionality of the bar, all I need you do to is add a buffering sub-bar, for example, on YouTube the white progress bar is what I consider the buffer bar. Other than that I need really simple stuff, a progress bar when uploading a video, adding a quality changing feature and a size changing feature, and gathering the info of a picture from the server. If your experienced/proficient in Django and JS, you should be done within 3 hours, this really shouldn't take long. We're going to use PayPal to payment, and either freelancer or Skype for messaging.
